改进的单点位移分量的t分布法及其在监测网稳定性分析中的应用

摘要

单点位移分量的t分布法是一种算法非常简便的稳定性分析方法,但有时这种方法无法搜索出所有的不稳定点。为解决这个问题,本文提出了对t分布法进行改进的方案,通过实例分析,对该方法进行改进后的稳定性分析结果优于改进前的方法,能够满足一般监测网稳定性分析的要求。%T distribution method of simple-point displacement is a very simple algorithm for stability analysis in monitoring network.However,this method sometimes can not find all the instable points.To solve this problem,a modified T distribution method is proposed.By example analysis,the result of this modified method is proved to be better than the original method,and this modified method can meet the requirements of stability analysis of normal network monitoring.
